US MacBook Air comparison

MacBook Air M4 vs MacBook Air M3 in the US (2026) — which should you buy

Apple launched the MacBook Air M4 in early 2025 with a meaningfully faster CPU, dual external display support and a lower starting price than the M3 Air had at launch, and a year later the M3 Air is still on sale in the US at meaningful discounts next to the M4's stable Apple.com price. For US shoppers the choice usually comes down to four things: whether dual external displays matter for your desk setup, how much you value the multi-core CPU jump for video and code work, whether the M3 Air's clearance or refurb price closes the gap, and whether the Apple Education Store cuts enough off the M4 to make the upgrade automatic. This page pulls the live US listings so you can see both prices side by side, and the comparison below lays out the meaningful differences so you can decide whether the upgrade is worth the money to you in 2026.

MacBook Air M4 vs MacBook Air M3 — at a glance

Spec / feature	MacBook Air M4 (2025)	MacBook Air M3 (2024)

Why US MacBook Air prices barely move off MSRP

Apple controls MacBook distribution tightly in the US: the official MSRP holds most of the year, and the real M4 vs M3 gap shows up through M3 clearance and refurb pricing at B&H, Adorama, Best Buy and Micro Center, plus Apple Education Store discounts on the M4 for verified students, parents and faculty. Amazon and Best Buy undercut on Prime Day and Black Friday. A static 'M4 vs M3' article goes stale within weeks — the live cards on this page read straight from the catalog.

Buying signals

What actually changes between the MacBook Air M4 and MacBook Air M3

Dual external display support is the headline change

The single biggest real-world difference for desk workers is external display support. The M3 Air requires the lid to be closed and only supports one external display natively. The M4 Air supports two external displays with the lid open — typically a 6K panel and a 5K panel, or two 4K panels depending on your docking setup. If your desk has a dual-monitor arm, the M4 is the first MacBook Air that actually drives both without a cludgy lid-closed workaround.

CPU and GPU uplift is meaningful but not dramatic

Apple rates the M4 CPU at around 30% faster multi-core than the M3 on the same power budget, and the GPU gains are in the 20-25% range. For browsing, schoolwork, light photo editing and coding the difference is hard to feel day to day; for sustained video editing, large codebases, and creative apps that lean on the Neural Engine, the M4 pays back the upgrade quickly. The M3 Air is still a strong machine — it is not slow, it is just one generation behind.

RAM options and the 8GB base trap

The M4 Air now starts at 16GB on most configurations, but Apple still sells an 8GB M4 Air at the entry tier. The M3 Air launched at 8GB across the lineup. If you plan to keep the machine past three years, run more than a dozen browser tabs, or work in creative apps, 16GB is the safer pick on either generation — and you cannot upgrade later. Apple charges a steep premium for the 16GB and 24GB steps at checkout; plan for it.

Apple Intelligence and the macOS runway

Both machines run Apple Intelligence, but the M4's faster Neural Engine makes on-device Apple Intelligence features noticeably snappier, especially the writing tools and image generation in supported apps. macOS support runway typically runs five to six years from release; the M3 Air launched in 2024 and the M4 Air in 2025, so the M4 buys roughly one additional year of macOS support on top of an already-long runway.

Battery life, weight and chassis

Apple rates both Air generations at up to 18 hours of video playback and 15 hours of wireless web. Real-world battery under mixed use is similar — the M4 has a small efficiency edge but it does not show up as a full hour of additional life. The chassis, weight and port layout are identical between the two generations; this is an internal upgrade, not a redesign.

What to check

How to pick in the US in 2026

✓Pick the M4 Air if you want dual external displays with the lid open, do sustained video or code work, or plan to keep the machine past four years. The M4's extra year of macOS support and the dual-display change are the two reasons to pay the upgrade.
✓Pick the M3 Air if you mostly browse, do schoolwork and light photo editing, and the M4 price gap is more than a couple of hundred dollars. The M3 is still fast enough for almost everything a college or general productivity user will throw at it; the savings are real.
✓Check the Apple Education Store first if you qualify — verified students, parents and faculty usually beat every third-party retailer on the M4 base configuration by a meaningful amount, and AppleCare is fully supported. The Education Store does not stock the M3 Air at a discount.
✓Configure your RAM and SSD deliberately at checkout: you cannot upgrade later. If you keep the machine past three years or run more than a dozen browser tabs, 16GB is the safe pick on either generation; the 8GB base is the most common Mac regret.
✓Buy from Apple Authorized Resellers (B&H, Adorama, Best Buy, Amazon-sold-by-Apple) for the full US Apple warranty. Costco and Micro Center sometimes run further discounts on specific SKUs but check the listing carefully — open-box and clearance SKUs have shorter return windows.
✓Avoid 'Used – Like New' M3 Air listings on eBay or unknown Amazon sellers unless the price is meaningfully below B&H or Adorama. The M3 still has years of macOS support ahead, but private sellers carry no Apple warranty and the battery may already be past 80% of its original capacity.

FAQ

MacBook Air M4 vs MacBook Air M3 in the US — common questions

Is the MacBook Air M4 worth it over the M3 in the US?

If you want dual external displays with the lid open, do sustained video or code work, or plan to keep the machine past four years, yes. For most everyday tasks — schoolwork, browsing, light photo and video editing — the M3 Air on sale or clearance remains the smarter buy.

How much does the MacBook Air M4 cost more than the M3 in the US?

Apple.com holds both machines near MSRP most of the year, so the price gap is roughly the difference between the M3 clearance stock at third-party retailers and the M4 base at B&H or Adorama. Live cards above show the current US floor; the gap narrows meaningfully around Prime Day and Black Friday.

How much RAM do I need on the MacBook Air M4 or M3 in the US?

16GB if you plan to keep the machine past three years, run more than a dozen browser tabs, or work in creative apps. The 8GB base is a real bottleneck on macOS today and is not upgradeable after purchase. Apple charges a steep premium for the 16GB and 24GB steps at checkout — plan for it in your budget.

Does the MacBook Air M4 come with AppleCare in the US?

AppleCare+ is sold separately — Apple includes a 1-year limited warranty. You can add AppleCare+ within 60 days of purchase, with cheaper monthly pricing available in some configurations. Apple Authorized Resellers (B&H, Adorama, Best Buy, Amazon-sold-by-Apple) also support AppleCare+ on machines bought from them.

Should I wait for an M5 MacBook Air in the US?

Apple has not announced an M5 MacBook Air at the time of writing. The M4 Air launched in early 2025 and typically sits in the lineup for around 18 months before a refresh; if you need a MacBook Air today, buy the M4 — the M3 clearance is the value alternative, not a wait for M5.

Do MacBook Air M4 and M3 bought in the US come with Apple warranty?

Yes — machines bought from Apple.com, Apple Authorized Resellers (B&H, Adorama, Best Buy, Amazon-sold-by-Apple, Micro Center), or an Apple Store carry the standard 1-year Apple limited warranty with the option to add AppleCare+ within 60 days. eBay and unknown Amazon Marketplace sellers often ship with no US Apple warranty; check listing language carefully before you click buy.
